7x + 6y < 42
6y < -7x + 42
y < -7/6x + 7
slope = -7/6....y int = (0,7)...x int = (6,0)...it will be a dashed line...shading will be below the line....so start at (0,7)...and since the slope is -7/6...go down 7 spaces and to the right 6 spaces, and keep doing this and u will cross the x axis at (6,0)
7x + 6y > - 42
6y > -7x - 42
y > -7/6x - 7
slope = -7/6...y int = (0,-7)....x int = (-6,0)....line will be dashed....shading will be above the line...so start at (0,-7) and since the slope is -7/6...go down 7 spaces and to the right 6 spaces...keep doing this and u will cross the x axis at (-6,0)
The common denominator is 18
Replace x with the x values of the choices and see if it solves to equal the y value:
Y=-7x + 2
A) (1,2)
Y = -7(1) + 2 = -7 + 2 = -5 not 2
A is wrong
B (8,-54)
Y = -7(8) + 2 = -56+ 2 = -54
This works out.
The answer is B
Answer:
Step-by-step explanation:
The cross section will have the same shape as the base of the pentagonal prism; the dimensions will be proportionally smaller.
